Heating your home can be a chore when the weather is this cold. But there are a few things you can do to keep the heat in and save a bit of money. Members of the Citizen’s Utility Board say sealing leaks in windows, doors, and exhaust fans will help. It’s also a good idea to clean or replace filters for a forced-air heating system. Circulate the heat with the help of a ceiling fan. In the winter, run the fan clockwise to pull warm air down from the ceiling.
